Feature request description

Please add automatic merge/cleanup .po language files when you update language template (.pot) file

• Merge every language with new template
• Remove from every language the obsolete strings
• Forced strings lenght to maximum lenght (ex. 400 chars) without word-wrap

use msgmerge to merge language files with templeate
use msgattrib to remove obsolete strings

msgmerge options = --update --width=400 --no-wrap -q
msgattrib options = --no-obsolete --width=400 --no-wrap

Not sure of the frequency of translation update...

But updating .pot each time seems wrong as we store location, and so many changes detected just for line number difference :-/

Updating .po from .pot seems less problematic. Issue I see is with (git) conflicts if someone is working for a translation.

Removing obsolete string might be unfriendly too, as sentences might be modified by minor changes (as codelite -> Codelite or typo) and so no more fuzzy help for translator.

no-word-wrap is stylistic (and I would agree with that change :-) )

Adding helper script in translation directory might be possible.

Currently, the Readme.md seems sufficient for that manual and punctual change.
